Hi all just a post to say I had a close call today. I almost stuffed my regulator because I didn't depressurise my keg. I've only just started natural carbing my kegs and I put one into my fridge today and thought I would give it a shot of noss just to see if it had held pressure. Not thinking that maybe the keg had more pressure than the bottle was set at I saw beer going straight up the gas line. Lucky it was only slow do I pulled it straight off, bled the keg and hooked it up again pushing the beer back out. Lucky. So says a few things to me, I've overprimed the keg a little, think about what ya doing and buy a bloody non return valve.
